Patent number: 9014683Abstract: A method and apparatus for performing a software upgrade are disclosed. The method determines a plurality of mobile endpoint devices affected by a wireless network access software upgrade, and schedules a deployment of the wireless network access software upgrade. The method transmits a notification to the plurality of mobile endpoint devices, wherein the notification is configured to cause each of the plurality of mobile endpoint devices to store user settings in a memory of each of the plurality of mobile endpoint devices. The method downloads the wireless network access software upgrade wirelessly to the plurality of mobile endpoint devices, wherein the wireless network access software upgrade is configured to cause each of the plurality of mobile endpoint devices to install the wireless network access software upgrade and to restore the user settings from the memory of each of the plurality of mobile endpoint devices.Type: GrantFiled: July 14, 2014Date of Patent: April 21, 2015Assignee: AT&T Mobility II LLCInventors: Yung Choi-Grogan, Jun Shen, Ming Zhang

Publication number: 20150065195Abstract: Radio network technology and display thereof can be managed when multiple services and radio network technologies are available to a multi-technology mobile device. Management relies at least in part on a subscriber profile that comprises a network selection profile constructed through market policy, subscriber policy, and application policy for radio technology utilization. Network preference(s) profile is generated on per subscriber, or per subscriber type, basis and is conveyed to a subscriber station over the air. Initial subscriber profile can be delivered at a time of provisioning a multi-technology mobile device, and updated based at least upon subscriber demand, a schedule established by a network operator or service provider, or an event related to coverage area relocation or contracted services. Radio technology preferences and display of associated technologies available to a multi-technology mobile device can be dynamically controlled on a per-call and/or per-application basis.Type: ApplicationFiled: November 7, 2014Publication date: March 5, 2015Inventors: Arthur Brisebois, Sharat Chander, Yung Choi-Grogan

Patent number: 8914034Abstract: The disclosed subject matter relates to an architecture that can provide enhancement with respect to circuit switched fall back. In particular, the architecture can reduce the signaling and delay of conventional systems that are necessitated by establishing a radio resource control connection prior to establishing the circuit switched fall back connection. For example, when user equipment is not in a radio resource control connected state at the time of a circuit switched fall back call, the radio resource control connection can be at least partially avoided by responding to a radio resource control connection request message with a radio resource control connection reject message that includes target cell reselection information.Type: GrantFiled: May 26, 2011Date of Patent: December 16, 2014Assignee: AT&T Mobility II LLCInventors: Weidong Hu, Inderpreet Singh Ahluwalia, Yung Choi-Grogan

Patent number: 8380207Abstract: A system and methodology that resolves complex mobility handling issues in Long Term evolution (LTE) networks, overlaid with Universal Mobile Telecommunications System (UMTS) macro and UMTS femtocells that share a common UMTS Absolute Radio Frequency Number (UARFCN), is provided. Moreover, an LTE user equipment (UE) includes a femto identification component that differentiates between the UMTS macro and UMTS femtocells by employing Location Area Code (LAC) data. In an aspect, the femto identification component ensures that the LTE UE connects to the UMTS femtocell as soon as the LTE UE enters the UMTS femtocell coverage area, even when the LTE radio frequency (RF) signal is deemed sufficient for communication. Further, the femto identification component ensures that the LTE UE stays connected to the LTE network, as long as possible, while outside of the UMTS femtocell coverage area.Type: GrantFiled: February 22, 2011Date of Patent: February 19, 2013Assignee: AT&T Mobility II LLCInventors: Yonghui Tong, Inderpreet Singh Ahluwalia, Arthur Brisebois, Yung Choi-Grogan

Publication number: 20130029635Abstract: Systems, methods, and apparatus that select a radio access technology based on a usage history are presented herein. A recording component can record, based on a first use of a wireless communication network, information identifying a radio access technology associated with the first use. A selection component can select, in response to receiving a request for a second use of the wireless communication network, the radio access technology for the second use based on the information. A transfer component can determine whether a request for a handover is based on a wireless service coverage. Further, the transfer component can determine whether a request for a reselection is based on the wireless service coverage. Moreover, the selection component can select another radio access technology for the second use in response to the request being based on the wireless service coverage.Type: ApplicationFiled: July 26, 2011Publication date: January 31, 2013Applicant: AT&T MOBILITY II LLCInventors: Yung Choi-Grogan, Jun Shen, Ming Zhang
